Research on High Temperature Oxidation Behavior of Zirconium Alloy for Fuel Element Based on MOOSE Platform

  • 摘要: 为建立新型N36锆合金高温氧化行为预测方法,使得自主燃料元件性能分析程序FORWARD能适用于失水事故(LOCA)工况。本研究开展了新型N36锆合金高温蒸汽氧化试验,建立了N36锆合金高温氧化模型并对其进行了验证,最后基于FORWARD程序对LOCA工况下N36锆合金的高温氧化行为进行预测。结果表明,预测得到的N36锆合金的氧化增重与验证试验结果较为符合,且预测的N36锆合金在LOCA工况下的高温氧化行为较为合理。因此,本研究建立的模型和燃料元件性能分析程序能够用于新型N36锆合金高温氧化行为的预测。
